MOLD FOR CASTING WASTE-TRAPS.

SPECIFICATION forming part of Letters Patent No. 617,396, dated January10, 1899.

Application filed January 27, 1897. Serial No. 620,886. (No model.)

To a/ZZ whom t may concern:

Be it known that I, PETER DAvID HAY, a citizen of the United States,residing at Detroit, county of Wayne, State of Michigan, have invented acertain new and useful Improvement in Molds for Casting Waste-Traps; andI declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

My invention has for its object an improved mold for castingwaste-traps; and it consists of the construction,combination,andarrangement of devices hereinafter described and claimed, andillustrated in the accompany- In the drawings, A denotes any suitablesupport or frame.

B B denote the counterparts of a two-part mold, hinged together, asindicated at b.

, C is the main or body core, removably engaged in said mold to form thebody of the trap.v This core may be actuated in any desired manner, asby a threaded stem C. This core O is preferably formed with a shell O2,inclosing two chambered bodies Cs and O4, within which is located arotatable shaft O5, with which are connected two elbow-cores D and D.the shaft C5 in any suitable manner to secure their advancement andretraction through the shell C2 of the core O, said shell beingconstructed with suitable orifices therefor, as indicated at c and o.

As shown in the drawings, the shaft C5 is formed with crank-arms, asindicated at c2, with which the elbow-cores are eccentrically Theseelbow-cores are engaged with connected, respectively. Said elbowcoresmight be eccentrically connected with said shaft in any suitable mannerto secure their advancement and retraction.' The bodies C3 and O4 arechambered, as indicated at c3 and c, to give room therewithin for theadvancement and retraction of the elbow-cores.

The mold is shown constructed with a main chamber to receive thebody-core C, with` a communicating chamber to receive an auxiliary coreto contact with the advanced elbowcore D, and with a communicatingchamber to receive another auxiliary core to contact with the advancedelbow-core D. Thus to form the main portion of the outlet-passage of thetrap I provide an outlet-core E, contacting with the advanced elbow-coreD' at its inner extremity, the opposite end being connected with thestem C', so as to be simultaneously removable with the main core O.

The core D may be formed with a socket at el to receive a pin e on thecore E to hold the parts together 'while the mold is being used.l

The shaft C5 may be actuated in any proper manner. As shown, the stem Ois made hollow, and the outer end of the shaft is sleeved therethroughto be actuated by a hand-wheel O6 to rotate said shaft.

To form the inlet-passage of the trap, I provide an inlet-core F, havinga stem F and operating-handle F2. The inner end of the core F contactswith the advanced elbow-core D. Said latter core maybe constructed Witha socket at d' and the core F with a pin f to engage the socket and holdthe parts in firmengagement.

The mold is journaled, as indicated at B2, upon the support A, so as tobe swung thereupon to actuate the mold.

The operation of the device is as follows:

The main core O having been advanced into the mold with the outlet-coreE, the shaft C5 is actuated to advance the elbow-cores D D.

The mold is then closed and swung upon its n IOO and the elbow-coresretracted, when the main core and core E may be withdrawn. The mold maythen be opened and the trap removed.

The core C being made with the shell inclosing the chambered bodies C3C4, it is evident that the shaft C and the elbow-cores may readily beengaged within said chambered parts before their engagement into theshell, when by retracting the elbow-cores the bodies may be engaged inthe shell, said shell being held in place by the cap C7 at the inner endof the stem C5.

It is evident that this mold may be operated by a single attendant. Thestem F of the core F rests upon the upper edge of the frame A, while thestem C contacts with the under surface of said frame. When the cores Cand E have been entered into the mold, the mold may then swing downwardupon its journals, when the core F may readily be entered. Then the moldhas been filled with metal, the core F may readily be removed by theattendant before the mold is swung back into horizontal position. Bythis mold one attendant can do the work which it has heretofore requiredthe services of two men to perform.

It is evident that inasmuch as the main core and the elbow-cores remainin the mold and form a part thereof in the act of casting the elbow-coremust have a tight joint when in advanced position with the adjacentportions of the main core through which it is advanced. By making theelbow-cores tapering they will seat closely when advanced, so as toeifectually prevent the molten metal flowing into the chambers of themain core. As shown, the elbow-cores are engaged on diiferent sides ofthe shaft and toward opposite ends thereof.

That I claim as my invention is l. In an apparatus for the purpose setforth, the combination of a two-part hinged mold, a main core, anoutlet-core, means extending to the exterior of the mold for supportingand simultaneously actuating the outlet-core with the main core, aninlet-core, and elbow-cores carried by said main core, and means foradvancing and retracting said elbow-cores, substantially as set forth.

2. In an apparatus for the purpose set forth, the combination of atwo-part hinged mold, a main core,an outlet-core, an inlet-core, a shaftcarried by the main core, and elbow-cores connected with said shafttoward opposite ends of said shaft, said elbow-cores retractable withinthe main core and advanceable therethrough by the operation of saidshaft, substantially as set forth.

3. In an apparatus for the purpose set forth, the combination of atwo-part hinged mold, a chambered main core, an outlet-core, aninletcore, a shaft carried by the main core and projecting therewithin,and elbow-cores eccentrically connected with said shaft, saidelbow-cores retractable within the main core and advanceabletherethrough by the operation of said shaft, substantially as set forth.

4. In a mold for a casting with several communicating cavities, incombination with the mold for the exterior of the casting, a core foreach cavity, an elbow-core for each communicating passage between thecavities, an actuating device adapted to actuate the elbowcores, andcouplings between the several elbow-cores whereby they movesimultaneously, the elbow-cores being located in one ofthe main cavitycores and being arranged to be projected therefrom and retractedthereinto, substantially as described.
